A "TNC Male to TNC Male Adapter" is a specific type of RF (Radio Frequency) adapter used for connecting two devices or cables with TNC (Threaded Neill–Concelman) male connectors. Here's what this term means:
"TNC Male": TNC male connectors are threaded RF connectors known for their durability and reliability. The "male" part means it has a pin or plug that is meant to be inserted into a female TNC connector.
"Adapter": This term signifies that the device is specifically designed to adapt two TNC male connections. It does not change the gender of the connectors; it merely joins two male TNC connectors together.
